[iOS] Stop terminating the prewarmed process on application suspension
https://bugs.webkit.org/show_bug.cgi?id=203033

Reviewed by Alex Christensen.

Stop terminating the prewarmed process on application suspension. Having no prewarmed process when the
application resumes means the next cross-site load will be significantly slower. If the system needs
memory, this process can be jetsammed.

(WebKit::WebProcessPool::applicationIsAboutToSuspend):
